This report explores 31 coal combustion waste sites that are known to have contaminated groundwater, wetlands, creeks, or rivers in 14 different states. At almost half of the sites, contamination extends off the power plant property at levels that exceed drinking water or surface water quality standards. In addition, 22 of the 31 sites are located in communities with high poverty rates. According to the EPA, residents near coal ash dump sites have a higher risk for cancer as well as damage to the liver, kidney, lungs, and other organs.
